During World War I, the German Army—formally known as the Deutsches Heer—entered the conflict as one of the most modern and disciplined forces in Europe. Germany’s military strategy at the war’s outset was built around the Schlieffen Plan, crafted by General Alfred von Schlieffen in 1905. The plan aimed to prevent a two-front war by quickly defeating France in the west through a massive flanking movement that would sweep through neutral Belgium and encircle Paris, before turning to face Russia in the east, whose mobilization was expected to be slower. However, the execution of the plan was flawed. Belgium's resistance, British involvement after the violation of Belgian neutrality, and unexpectedly rapid Russian mobilization forced Germany to divert troops eastward, contributing to the failure of the plan and the start of prolonged trench warfare on both fronts.
German soldiers, referred to as Landser, began the war wearing traditional uniforms that reflected 19th-century styles. Their standard issue included the feldgrau (field-grey) wool tunic and trousers, which were initially intended to offer some degree of camouflage. A distinctive feature of the early war uniform was the Pickelhaube, a leather spiked helmet with brass fittings, designed more for parade than protection. As the war dragged on and conditions in the trenches grew more brutal, the impractical Pickelhaube was gradually replaced by the Stahlhelm—a steel helmet introduced in 1916 that provided much better protection against shrapnel and bullets. Uniforms also evolved, with simplified designs, sturdier fabrics, and better-suited gear for mud, cold, and constant shellfire. Soldiers carried basic equipment including a rifle (often the Mauser Gewehr 98), ammunition pouches, an entrenching tool, and a gas mask as chemical warfare became more common. The German Army's early confidence gave way to a grinding war of attrition, where adaptability, endurance, and industrial support became just as crucial as initial planning.
